What the Gaga?

What the Gaga is Lady Gaga talking about?

Lady Gaga has been playing stadiums and arenas around the globe for months and will return to the U.S. on July 1 with her 'Monster Ball Tour.' Yesterday, the 'Poker Face' singer announced even more North American dates for 2011 -- but don't say she's working too hard. She addressed rumors her non-stop touring is wearing her out while performing 'Speechless' in Sweden.

"You know when people say, 'Lady Gaga's really tired, she needs to take a break,' I just think about all those times I sang in bars when nobody was singing my lyrics. I'll sleep when I'm dead, okay?"
